STRUCT QAIC_MANAGE_TRANS_ACTIVATE_TO_DEV(9)

✨ struct qaic_manage_trans_activate_to_dev — Kernel API Manual ✨

okay bestie, welcome to the struct qaic_...ivate_to_dev(9) page 💅 this is a Kernel API Manual entry, and honestly? it's giving "tiny struct, big main character energy." let's get into it 🫶

---

🌸 NAME 🌸

struct qaic_manage_trans_activate_to_dev — literally just defines an activate request. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

here's the whole thing, no cap, exactly as written:

struct qaic_manage_trans_activate_to_dev {
    struct qaic_manage_trans_hdr hdr;
    __u32 queue_size;
    __u32 eventfd;
    __u32 options;
    __u32 pad;
 };

---

🎀 Members 🎀

okay so let's meet the cast 👑

• hdr — In. the header that identifies this transaction. it's the little name tag so everyone knows what's going on iykyk 🏷️
• queue_size — In. the number of elements for the DBC request and response queues. so basically how big the queues are. iconic. 📏
• eventfd — Unused. 💀 not me pointing at it and going "girl, same." it's just… there. unused. that's the whole description. we respect it though 🙈
• options — In. device specific options for this activate. nice and customizable, we love device specific ✨
• pad — structure padding. Must be 0. that's not a suggestion bestie, that's the rule 🚨
